 a second device, comprising:
 one or more second processors to:
 receive the indication from the first device; and 
 determine, according to the indication, instructions for timing for the first device to transmit the plurality of data packets from the buffer. 
 
 
 
     
     
       11. The system of  claim 10 , wherein the first device comprises a wireless communications interface configured to:
 operate, for wireless data reception, in an on mode or an off mode; and 
 transmit the indication of the remaining time during operation in the on mode. 
 
     
     
       12. The system of  claim 10 , wherein the plurality of data packets have a fixed periodicity. 
     
     
       13. The system of  claim 10 , wherein the one or more first processors are configured to generate the indication of the remaining time to include an offset between a start time of reception by a wireless communications interface of the first device and a start time of transmission of at least one data packet of the plurality of data packets. 
     
     
       14. The system of  claim 10 , wherein the one or more first processors are configured to transmit, using a wireless communications interface of the first device, the indication of the remaining time for transmission of at least one data packet of the plurality of data packets prior to transmission of the at least one data packet to the network device. 
     
     
       15. The system of  claim 10 , wherein the plurality of data packets comprise a plurality of protocol data units (PDUs) arranged as a plurality of PDU sets.
